12 Claims.

This invention relates to washing devices, particularly to devices for cleaning tanks with liquids, and the like devices.

An object of this invention is to provide a device of the character described comprising a member provided with a pair of oppositely extending nozzles and means activated by the pressure of the liquid passing through the nozzles to simultaneously rotate said member about its axis and about an axis perpendicular to its axis.

Yet another object of this invention is to provide a, device of the character described provided with a water wheel rotatable by liquid pressure and said water wheel being removable as a unit from said device for cleaning or replacement. The construction of the drive is positive, it is gear driven throughout and there are no springs to get out of order thereby cutting maintenance to a minimum. Main body casting is provided with means to control the volume of water, or liquid passing through. Bottom of rotating body and end of nozzle body are sealed with caps to reduce leakage to a minimum, thereby cutting down amount of water to be pumped out of bottom of tanks or compartments.

Still another object of this invention is to provide a device of the character described which will operate under a relatively large range of liquid pressures, either high or low pressures.

A still further object of this invention is to provide a device of the character described comprising a member rotatable about an axis perpendicular to its axis, a second member rotatable on the first member about the axis of the latter and provided with oppositely extending nozzles, means to rotate said first member about an axis perpendicular to its own axis, means to rotate the second member about the axis of the first member, and means to permit limited free movement of the second member about the axis of the first member. The rotation of the nozzle member is at a rate difierent than that of the body so as to permit progressive change in point of contact of liquid against compartment or tank.

Yet another object of this invention is to provide a device of the character described comprising a liquid inlet body adapted to receive liquid under pressure, a housing attached to said inlet body and said body being formed with an opening communicating'with said housing, a water wheel mounted for rotation in said housing and projecting through said opening into said body, a second body mounted for rotation about the axis of the first body and extending at right angles thereto and communicating with the first body,

expensive to manufacture, sure and positive in operation, easy to manipulate, and yet practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter described, and of which the scope of invention will be indicated in the following claims.

Flange' 84 is'formed with a 'rimbomplem'entary toand having lapped engagement with the: flanged rir'n BO of hous'in'gp'ai't '14. The hous ing' part 83 i ha's' a;'-si'1r f2;ce as contacting the re: maining half of the surface "l1 and it is attached" thereto by'the' screwsi921? Housing 83 comprises a thickened wan as rermea' winr a through opening- '8| coaxialwith the opening 82 Extending froz'n sa'id wan '8G is'a' curve'd sub stantially quarter amiul'a'i' 'wall' 88 from w'h'ich extendsa' flat wall portion 89?

Extending: through the' openings '82} 81 and traversing :the" space between walls 18 and '86 is a shaft one end" of whicn'isreeeived: 1mm I opening 82;- The' shaft I00 asses entirely throughthe through" opening 81 in the 'wall- 1 8B and it is formed at'its outer end with'an enema: gear l M projecting into th'e chamber I 02 forf11ed by walls 86, 88, B9, 90, 92 and 93. Attached to the outer edges of said walls 89, 90, 92, 93 by means of screws I03 or in any other suitable manner, is a closure cap I04 closing the chamber I02. The cap I04 is formed with an outwardly recessed part-cylindrical wall I05 ofiset from the axis of the shaft I00. It is also formed with a pair of outwardly recessed hubs I06 and I! formed with blind openings I08 and I09 respectively, parallel to one another and to the shaft I00, but ofiset therefrom.

Wall 86 of housing member 83 is formed with a pair of blind openings I08a and I090. aligned with the openings I08 and I09 respectively. Traversing chamber I02 is a shaft IIO. Journaled in the openings I08, I08a and fixed thereto is a pinion III meshing with the gear portion IOI. Fixed to the pinion III for rotation therewith is a smaller pinion II2. Fixed to the shaft I00 and disposed within the chamber I00a formed by walls I8, I9, 84 and 86 is the water wheel or motor 'II. Said water wheel comprises vanes II3 projecting through the opening I4 and into the inlet pipe I2. The vanes II3 are in the form of cups and they are so positioned to receive the impact of water passing through the pipe portion I2. The vanes project to a position below the axis of the pipe portion I2 so that part of the water pressure rotates the water wheel while permitting the water to pass through the pipe portion I2 to the slots 22.

Journaled in the openings I09, I09a is a shaft II5. Fixed thereon, in any suitable manneris a pinion II6 meshing with the pinion II2. Also fixed on said shaft H is a worm II'I. naled in the openings 91 and 95 of walls 92, 93 respectively, is a shaft I20. The shaft I is also journaled in the opening 21 of member II. Fixed on the shaft I20 and disposed Within the chamber I02 is a worm wheel I2I meshing with the worm II'I. Worm wheel I2I projects into recess I05. Fixed to the shaft I20 is a pinion I22 contacting the inner end of the hub 26. Also on said shaft and adjacent the pinion I22 is a second pinion I23 of somewhat larger diameter.

The pinion I23 is likewise fixed to the shaft I20.

It will now be understood that when water under pressure passes into the inlet pipe II, the water wheel or motor II will be rotated, thereby rotating shaft I00 and pinion IOI, which in turn will rotate pinions I I I and I I2, and hence pinion I I6 and shaft H5. Rotation of shaft I I5 will rotate the worm wheel I2I through the worm II'I. Shaft I20 and pinions I22, I23 will therefore likewise be rotated. The gearing 13 described herein, it will be noted, is a speed reduction gearing.

Fixed to the outer end of the sleeve portion 36 of member 3I is a gear I25 meshing with the pinion I22. Gear I25 is countersunk to receive the outer end of the sleeve 36 and is fixed thereto by means of screws I26. Said gear contacts surface 29. Rotatably mounted on said sleeve 36 and interposed between the gear I25 and the shoulder 36a formed at the inner end of sleeve 36 is a gear set I comprising a gear I3I meshing with the gear I25 and a bevel gear I32 fixed to said gear I3I. Rotatably mounted on sleeve portion 46 is a bevel gear I33 meshing with the bevel gear I32. Extending upwardly from the bevel gear I33 is a sleeve I34 surrounding the upper portion of sleeve 46 and spaced therefrom, and provided with a pair of diametrically disposed radial inwardly extending lugs I35. dis- J ourposed in the circular path of the lugs 53 on said sleeve 46.

It will now be understood that rotation of shaft I20 and pinions I22, I23 will cause rotation of gear I25 and the gear set I30. Rotation of the gear I25 will cause rotation of T member 3! and chambered member 45 together about the axis of member II. Rotation of the gear set I30 will simultaneously cause rotation of member 45 about the axis of pipe portion 31. It will be noted that rotation of the bevel gear I33 will time turn the water wheel to cause rotation ofthe nozzles about the axis of the nozzle member 45, and also at the same time about the axis of the inlet member II.

The rotation of the nozzle member is at a different rate of speed than the speed of rotation of the body, so as to permit a progressive changing of point of contact of the liquid against the compartment or tank. For this purpose bevel ears -32 and I33 have different number of teeth.

It will be further noted that the entire housing 70 together with the water wheel and the reduction gearing 13 may be removed as a unit by first removing the screws I9, I91: and slipping the gears I22, I23 off the shaft I26.

Inserted into the inlet body portion I2 is a flow control member I40 held in place by a set screw MI screwed within a threaded opening I42 in said body I2. Said member I40 is formed with a longitudinal slot I43 into which the rotating vanes II3 project. The flow control member I40 cuts down the amount of water which passes through the cleaning device. The control mem-.

ber I40 has a cylindrical outer surface so as to fit within the body I2.

It will thus be seen that there is provided a device in which the several objects of this inven-.

tion are achieved and which is well adapted to meet the conditions of practical use. 7
